| Abstract Scope |
This study examines electron beam welding in high-temperature applications in advanced ultra-supercritical (AUSC) power plants utilizing P91 steel and Incoloy 800HT. The major goal is to examine the microstructural and mechanical behavior of the welded joints at high temperatures up to 650 °C. The process involved welding joints and high-temperature tensile testing to evaluate their mechanical properties. The major findings show that electron beam welding parameters significantly affect dissimilar metal tensile strength and ductility. The results explain base metal working temperatures' impacts and limitations. Serrated flow and substantial plastic deformation were seen on the Incoloy 800HT side before failure. Heavy carbide precipitation at high temperatures impaired the dissimilar metal weld's mechanical strength. Materials science and engineering benefit from this study because it improves the reliability and integrity of dissimilar metal junctions for high-temperature applications in many different fields. |
